Black drawing leads for illustration. The key components of these leads are the pure, micro-pulverized natural substances on a base of calcium carbonate. Together with top-quality additives and binding agents, a perfect base mixture is created into which colour pigments are carefully mixed. The pigments are sourced from all over the world and their quality, light permanency and dosed concentration influence the final result as well as the durability of the artworks. They are therefore suitable for detailed drawing.
